Doesn't the installer tell you that the firmware needs to be updated? I 
seem to remember always seeing a warning saying something like "You may 
see a message indicating that your firmware needs updating, if you get 
this message follow the directions to update before running the 
installer...." something like that. I have installed on a few different 
machines including an older iMac  ( a 350) and have had no problems.
